摘要

Food security is becoming increasingly important as the world's population grows, and the likelihood that climate change could impair agricultural supply complicates matters further. However, plants actively suppress growth as an adaptation strategy to enhance survival under stress conditions. Phytohormone jasmonates (JAs) regulate various physiological processes, including plant growth, development, and senescence. Plant biotic and abiotic stress responses cause dynamic shifts in the metabolism and signaling of JAs, suggesting that JAs response impacts plant development and resistance to various stresses. The JAs-associated responses depend on core components of JAs -signaling, including the transcriptional repressors protein JAZ and the transcription factor MYC2. While traditional breeding has greatly benefited the world, this approach has several disadvantages, such as the emergence of undesirable traits and species barriers. Genome editing technology has revolutionized plant biology research and has significant ramifications for agriculture and global food security, particularly in light of climate change and population growth. CRISPR/Cas9 and its derivative tools have been used for genome editing in numerous crops to improve or alter desired plant phenotypes. This review summarizes JA's role in plant stress and defense and how CRISPR/Cas9-editing technology modifies plant JA's responses, especially against biotic and abiotic stress.
